HOT-WATER RADIATOR.

Specification of Letters Patent No. 19,591, dated March 9, 1858.

To all whom t mag/ cncerm I Be it known thatl I, Trios. T. TAsKEmofPhiladelphia, in the county of Philadelphia and State of Pennsylvania,have invented an Improved Mode of Putting Toget-her the Series of Tubesfor Radiators in Steam or Hot-Water Furnaces, and that the following isa full, clear, and exact description of the principle or character whichdistinguishes it from all other things before known and yof the usualmanner of making, modifying, and using the same, reference being had tothe accompanying drawings, of which- Figure l, is an elevation of theentire radiator. Fig. 2 a perspective View of one of the series of tubesof the radiator, and Fig. 3, a detached view showing the manner ofuniting the several series of tubes.

My invention consists in an improved mode of putting together boiler andradiator tubes in furnaces for warming buildingsl by hot water or steam,described as follows.

A represents a single series of tubes of the radiator composed of anumber of tubes a joined toget-her, and having free 'communication witheach other by means of the tubes C, D, and the end or terminal sectionsE.

Y These sections are fitted to each other by the shoulder and flangejoints E, F, andI are bound firmly together by the through bolt H, whichpasses through all the sections and is tightened by mea-ns of the nutsK, the

joints being all made tight by washers of vulcanized rubber or othersuitabl-e material. By this mode of securing the several series oftubes, I gain not only great advantages in the increased facility ofputting together the radiators and economy of construction, but I alsoobviate the leaks which are so common in other radiators as aconsequence of expansion and contract-ion from changes of temperature.The through bolt being surrounded by hot water or steam expandsimmediately on the first application .of heat and thus prevents thebreaking of the bolts or the forcible stripping of the screw threads bythe expansion of the tubes.

I am aware that sections of tubes with and without flange and shoulderjoints have been secured together by through bolts, and'I lay no claimto this mode of securing parts of a tube together, but what I claim 1s-The mode of securing together the several divisions or systems ofradiator tubes as herein set forth, the same consisting in theemployment of the four terminal sections E to each division, the wh'odebeing held together by the through bolts H as set forth, therebyaffording great facility in setting up the radiators and in taking themapart.
